Main and auxiliary circuits use screw-type terminals. For the main contacts, the terminal accepts 2x (1 to 2.5 mm²) solid/stranded or up to 2x 10 mm² maximum. Auxiliary terminals handle 2x (0.5 to 1.5 mm²) solid, 2x (0.75 to 2.5 mm²) stranded, or max 2x 4 mm². ## Motor Ratings and Switching Capacity Rated motor power reaches 7.5 kW at both 500 V and 690 V, 50/60 Hz. AC-2 duty at 400 V is 5.5 kW, covering slip-ring motor starting. The AC-4 rating of 12.5 A at 400 V defines the contactor's capability for plugging or jogging applications — this is the figure that governs real reversing duty, not the higher AC-3 or AC-1 numbers. Auxiliary contact switching capacity is specified across the control voltage range: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V DC. These values cover both AC and DC pilot circuits for PLC outputs or relay coils. These values assume a prospective short-circuit current typical for industrial panels. Mechanical endurance is typical 10 million operations. This is the figure for the contactor mechanism itself, not the electrical life under load — electrical endurance depends on switching current, voltage, and duty cycle.","metaTitle":"Siemens 3RT1024-1AK60 SIRIUS Power Contactor, Size S0, 7.5 k","metaDescription":"Siemens SIRIUS 3RT1024-1AK60 power contactor, Size S0, 7.5 kW at 500/690 V, AC-4 12.5 A, screw terminals, DIN rail mount, IP20 front.
